TOSOG Yellow Plant Solutions – Your sourcing partner for earthmoving machinery differentials and heavy equipment spare parts in South Africa.
Heavy Equipment Differential Parts and Assemblies
A differential is an essential component of a machine’s drivetrain. It distributes torque to the driven wheels while allowing them to rotate at different speeds when cornering or travelling over uneven terrain. In heavy equipment, the differential must withstand high loads, shock forces, demanding operating conditions and continuous work cycles.
TOSOG assists with sourcing differential assemblies and associated components for a range of heavy-duty machinery applications.
Our differential product range may include:
- Complete differential assemblies
- Differential gear sets and spider gears
- Crown wheel and pinion sets
- Differential carriers and housings
- Side gears and cross-shaft components
- Differential bearings and bearing kits
- Thrust washers and shims
- Oil seals, O-rings and gaskets
- Axle differential components
- Final drive and drivetrain-related components
Availability and compatibility depend on the machine make, model, serial number and required specification.

Differential Manufacturers and Replacement Parts
Selecting the correct manufacturer and specification is essential for dependable drivetrain performance. TOSOG assists customers in identifying suitable replacement parts based on the original equipment specification and the machine’s operating requirements.
Genuine OEM Differential Parts
Original equipment manufacturer parts are supplied under the relevant manufacturer’s specifications and are generally selected when exact original-equipment conformity is required. Availability, lead time and pricing depend on the manufacturer and part number.
OEM-Equivalent Differential Components
OEM-equivalent components may provide an alternative where dimensional accuracy, material quality, gear specifications and application compatibility are verified. Confirm the manufacturer’s documentation and warranty conditions before ordering.
Aftermarket Differential Parts
Aftermarket differential gears, bearings, seals and assemblies may offer additional sourcing options for older machinery, fleet maintenance and cost-sensitive repairs. Quality and compatibility can vary between manufacturers, so verify specifications before purchase.
Reconditioned Differential Assemblies
Where available, reconditioned differential assemblies can be considered for selected machinery applications. Confirm the extent of the rebuild, replacement components, inspection procedures and warranty coverage before committing to a purchase.
TOSOG can assist with enquiries involving differential and drivetrain products associated with manufacturers and brands such as Caterpillar, Komatsu, Volvo, Bell Equipment, ZF, Dana, Carraro and other relevant drivetrain suppliers, subject to application and sourcing availability.
Brand names are used for identification purposes. TOSOG’s supply of any particular brand or component is subject to confirmation, and no manufacturer affiliation or authorised dealership status is implied unless expressly confirmed.

Tips for Buying the Correct Differential
Buying the correct differential for heavy equipment requires more than matching the machine brand. Differences in axle configuration, production series, gear ratios and serial-number ranges can make apparently similar components incompatible.
1. Confirm the Machine Model and Serial Number
Provide the complete machine make, model and serial number. This helps identify the correct parts catalogue and applicable assembly.
2. Obtain the Original Part Number
If possible, provide the OEM part number from the existing differential, parts manual or manufacturer documentation. Part numbers should be verified against the machine’s serial-number range.
3. Identify the Axle and Differential Assembly
Record the axle manufacturer, axle model, identification plate details and differential assembly number. This is particularly important for machines fitted with third-party drivetrain systems.
4. Check the Differential Ratio
The crown wheel and pinion ratio must match the machine’s specified drivetrain configuration. An incorrect ratio can cause drivetrain problems and may damage related components.
5. Decide Between a Complete Assembly and Individual Parts
A complete differential assembly may be appropriate where internal damage is extensive. For localised wear or failure, replacing specific gears, bearings, seals or related components may be more suitable after inspection.
6. Check the Operating Conditions
Mining, quarrying, heavy hauling and continuous earthmoving place significant demands on differential components. Consider the machine’s workload, operating environment and maintenance history when choosing a replacement.
7. Compare Total Cost, Not Just Purchase Price
Consider the component price, shipping, import duties where applicable, lead time, warranty, installation and potential downtime. A lower initial price may not represent the best overall value.
8. Verify Warranty and Delivery Terms
Before placing an order, confirm product condition, warranty coverage, delivery arrangements and expected lead time in writing.
9. Avoid Ordering on Visual Similarity Alone
Similar housings or gear dimensions do not guarantee compatibility. Confirm the part number and technical specification before authorising the purchase.
